JACKSON JOHNSON, OF ROCHESTER, NEW YORK.

SPEOTFICATION forming part of Letters Patent No. 786,646, dated April 1,1905. Application filed February 24, 1904. Serial No- 195,107.

To add whom it may cancel-It.-

Be it known that I, JAoksoN Joinrsorr, a citizen of the Dominion ofCanada, residing in the city of Rochester, in the county of Monroe -andState of New York, have invented a new and useful Vertical CombinationShear-Gage for Cutting and Marking, hereinafter known as JohnsonsPerfection Combination Shear- Gage, of which the following is aspecification.

My invention relates to improvements in shear gages wherein a doubleadjustable clamp with pivoted and sliding connection is carried on avertical bar which has a detachable base. Thus the combination of theseand other detachable parts is used in conjunction with a pair of shearsor otherwise, Figures 1 and 2.

The objects of my improvements are, first, to obtain the correct anduniform length of a ladys skirt; second, to obtain the uniform width ofstrips of cloth in cutting; third, to locate buttonholes, &c..equidistant. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Fig. 1 is a perspective view of part ofthe combination in conjunction with shears for trimming the bottom of askirt. Fig. 1 is a view of the triform arm removed. Fig. 1 is a view ofthe guide-wire removed. Fig. 1 is an edge view of the graduated bar.Fig. 1 is aface view of the same. View of the base-plate. Fig. 1 is aplan view thereof. Figs. 1, 2 show in side and edge views the removablespring-clasp designed for use with the clamp seen in Fig. 1 Figs. 1", 23 show in top. side, and edge view the clamp. Fig. 2 is a perspectiveview of the entire combination for marking the bottom of a skirt. Fig. 3is a horizontal view of parts of the combination E, C, and B in Fig. 1,used in conjunction with shears for cutting strips of material ofuniform width, also in conjunction with buttonhole-shears to locate theholes equidistant.

'lhroughout similar letters refer to similar parts.

The clamp member E, Fig. 1, has a pin N in one side and a set-screw G,Big. 2, in other Fig. 1 is an edge side entering small dents in. theends of the rivet or screw which holds the shear-blades together, thusafi ording means of pivoted detachable connection with shears or otherappliance, as shown in Fig. 1 and Fig. 2. The clamp member E has alsotwo embossed loops O, which afford means of sliding on and detachablyclampin it to the vertical bar C by the use of set-screw H. The verticalbar 0 is supported in a vertical position on detacha'ole base F by meansof guide-wire B passing through the two embossed loops L and through theend of the vertical bar U. Thus guide-wire B and triform arm A (whichalso passes through one embossed loop M) form additional area of base.The combination thus assembled, as in Fig. 1, forms a gage by which, inconjunction with shears or other appliance, the uniform length of askirt is obtained by cutting or otherwise. (See Figs. 1 and 2.)

As seen in Fig. 3, the device is adapted for cutting folds and othernarrow pieces of clcth of uniform width. The guide B is run along theedge of the cloth and the shears sever the goods, making all strips ofuniform width.

In Fig. 2 the device is arranged to form a gage for making a line aroundthe bottom of a shirt at any desired point within eight inches from thefloor. The graduated arm C extends vertically from the base F, as inFig. 1, the clamp member E in this instance forming acrayon-holder, thecrayon S being held in the clamp member E by a removable spring-clasp D,seen detached in Fig. 1 and held by the set-screw G.

In the use of the form seen in Fig. 1 the device may be stationary andthe skirt moved with relation thereto, or vice versa, and in marking thebuttonholes with the device, as in Fig. 2, the same course may bepursued.

What I claim my invention, and wish to secure by Letters Patent, is-

1. A graduated bar, a wire arm B carried ed with said bar, a clampmember adjustable on said bar, and means in the clamp member for holdingthe article to be carried thereby.

2. A graduated bar, a wire 3 carried at one end thereof, a base, an armdetachably supat one end thereof, a base detachahly connectl l l 1 saidbar, and means in said clamp member 10 whereby said clump member willhold either a cutting-tool or a crayon-holder, as and for the purposespecified.
